Study Overview
Brief Summary
REBOOT is a pilot randomized trial of a repeated-dose brief intervention to reduce overdose and risk behaviors among naloxone recipients (REBOOT). It includes an established overdose education curriculum within an Informational-Motivation-Behavior (IMB) model. This study will test the feasibility of an efficacy trial of REBOOT vs treatment as usual (information and referrals) that will evaluate overdose events (non-fatal or death), drug use cessation, and overdose and HIV risk behaviors, among opioid-dependent persons who have previously overdosed and already received take-home naloxone (the opioid antagonist used to reverse overdose).

Outcomes
Primary Outcomes
Feasibility of a randomized trial with REBOOT
Time Frame: 16 months
To determine feasibility of a randomized trial with REBOOT, we will calculate screening and visit completion rates from the study database, with exact 95% confidence intervals (CIs), overall and by arm. Between-group differences will be assessed using Fisher's exact and Wilcoxon ranksum tests. We will calculate Kaplan-Meier curves for time to dropout, by group, and test for differences using the log-rank test.
Acceptability of REBOOT
Time Frame: 16 months
To determine acceptability of REBOOT, we will calculate counseling completion rates from the study database by visit, and tabulate the proportions of active arm participants attending 0-4 counseling sessions. Via ACASI, we will inquire about participant satisfaction with the intervention and belief that it affected their drug use behaviors; responses will be presented as means, medians, or proportions, as appropriate, with 95% CIs.
Influence of egocentric social network characteristics on overdose events and naloxone use
Time Frame: 16 months
To evaluate the influence of egocentric social network characteristics on overdose events and naloxone use, we will use GEE Poisson models with robust standard errors to evaluate the association between network size, evaluated at baseline and each return visit, and numbers of experienced and witnessed overdose events in the same period; zero-inflated models will be used if needed. In addition, we will explore the influence of homophily and assortativity on experienced and witnessed overdose events using similar methods. Newman's method will be used to calculate assortativity coefficients, a measure of the degree of demographic and risk behavior similarity within participants' egocentric networks.
